Rock of the Month

Anna Creek SandstoneThe importance of grass and acacia seeds as grain for grinding to flour led to substantial demand by Aboriginal groups in the desert for replacement grinding slabs. In some areas, this demand was met by specialised grindstone quarries, which fed finely finished millstones into the long-distance exchange networks snaking across the interior. The most striking concentration of these millstone quarries is in the southern part of the Lake Eyre basin, where there are at least 10 quarries including major complex at Anna Creek, Tooths Nob and Innamincka.
